No. 921,32e.

Specification of Letters Patent.

Patented llIay 11, 1909.

To all whom it may concern:

Be it known that I, CHARLES J. Wnmrun, a citizen of the United States, residing at Sidney, in the county of Shelby and State of Ohio, have invented certain new and useful Improvements in Corn-Shellers, of which the following is a specification.

My invention relates to improvements in corn sheller-s, and has for its object especially the provision of improvements foradjusting the shaft upon'which the sheller is mounted. Adjustment longitudinally should be provided for the shaft in the corn sheller so as to accommodate the same to wet or dry corn, as the space between the conical sheller member and the auxiliary shelling teeth of the casing should be different in the one case from that required in the other.

My improved means for adjusting the shaft is simple in its construction and is made so that it may be attached to a corn sheller frame very readily; it consists in the parts and their combinations hereinafter more particularly described.

Referring to the drawings which are hereto attached and hereby made a part of this specification, Figure 1 is a perspective of a corn sheller having my improved adjusting means for the shaft; Fig. 2 is a plan view of my improved adjusting means in place, partly broken away; Fig. 3 is a side view of my improved adjustingmeans in place.

In the drawings in which the same numeral indicates the same part throughout, 1 is a supporting frame, 2 is the casing mounted thereon having the hopper 8, and the fan discharge portion at, the shaft being shown at 5, and the driving pulley being indicated at 6. Theshaft 5 is mounted in the bearing 7 on the frame piece 8 at one end, and at the bearing 9 at its other end. Fixed upon the shaft, but not shown in the drawings, is the usual conical sheller member, and on the interior of the casing are provided lugs or teeth opposite the teeth of the sheller member, and the grain being carried forward by the conical member and the rows of teeth thereon, is shelled from the cob as it passes from the hopper to the discharge portion, in a well known manner. Experience has shown that the conical sheller member should be longitudinally adjustable in the casing, so that the annular space between the sheller member and the casing may be increased or diminished, as may be demanded by the condition of the grain, it being well known that Wet corn requires a difierent adjustment from that demanded by dry corn. To accomplish this longitudinal adjustment of the shaft 5, I mount upon the frame piece 8 of the frame 1 a bracket 10, so constructed that it may be readily attached to the frame 8 by means of the bolts 11 and 12, and may readily be detached therefrom when desired.

At 13 in the bracket 10 I provide a bearing, through which I project the screw 1 operated by the hand wheel 15; carried by this screw at its inner end is the yoke shaped member 16 slotted as shown at 17, to receive pins 18 and 19 carried by the collar 20, loosely mounted on the shaft 5. Secured to the shaft 5 by the set screw 21 is a collar 22, and also secured upon the shaft by the set screw 23 is the collar 24:, the loose collar 20 being mounted upon the shaft between the fixed collars 21 and Qt.

If the yoke shaped member 16 be moved inwardly or outwardly, it is readily seen that the shaft will be correspondingly moved, and as is readily seen, the inward and outward movement of the yoke 16 effected by the operation of the hand wheel 15 through the screw let. The shaft may be thus manipulated, whether it is stationary or in operation, for the reason that the collar 20 being mounted loosely thereon will not rotate, and may therefore be actuated to move the shaft in either direction by its engagement with the adjacent collars. The adjustment of the sheller as demanded by the degree of moisture in the grain can be readily accomplished at any time it is required, without stopping the sheller and without manipulating any of the parts or adjusting or removing the same, further than to rotate the hand wheel 15.

The means I have herein shown and described for adjusting the shaft are easily made and applied or removed, and are not complicated in their construction and are not easily put out of order. It is noted that the yoke member 16 is readily lifted from the pins 18 and 19, and removed from the shelling apparatus, whereupon the collars mounted on the shaft may easily and quickly be removed.

I do not confine myself to the specific construction herein shown but desire to claim any modifications thereof which are Within the spirit of my invention.

What I claim is:

In a corn sheller having an adjustable shaft and a sheller member carried thereby, adjusting means for said shaft comprising a collar loosely mounted adjacent to one end thereof, stops for said collar on said shaft, pins projecting from said collar, a yoke member formed with transverse slits therein adjacent to its ends for receiving said pins whereby said yoke member is supported at its inner ends, a screw mounted in the frame of said sheller member and engaging said yoke member at a point midway between the ends thereof and thereby supporting the same, and means for actuating -said screw whereby said yoke is moved to position the shaft inwardly or outwardly as desired.

In testimony whereof I affix my signature in the presence of two witnesses.
